Abstract

The invention relates to the technical field of intelligent weighing mechanical equipment, and discloses a weighing supporting roller for a belt weigher. The weighing supporting roller comprises a fixed plate, a fixed frame is fixedly arranged on an upper surface of the fixed plate, a fixed shaft is fixedly arranged in an upper part of the fixed frame in a sleeving manner, the supporting roller ismovably arranged on the outer surface of the fixed shaft in a sleeving manner, and a transfer belt is in friction and transmission with the upper surface of the supporting roller. Through the weighing supporting roller on the belt weigher, the supporting roller can automatically rotate under the effect of magnetic field force by adopting the magnetic field force between a first coil and a secondcoil which have the opposite winding directions, thereby producing a certain power for the transmission of the belt; a motor works to drive the belt to transmit, the consumed power is large, the gravity of the belt and the friction force between the belt and the supporting roller need to be overcome, auto-rotation of the supporting roller can counteract the friction force between the supporting roller and the transfer belt, the transmission pressure of the motor is reduced, the power required by the power transmission is reduced, and the service life of the motor is improved.

Description

technical field [0001] The invention relates to the technical field of intelligent mechanical equipment, in particular to a weighing idler used on a belt scale. Background technique [0002] The belt scale is an automatic weighing instrument that continuously weighs the bulk materials on the conveyor belt without subdividing the mass or interrupting the movement of the conveyor belt. The weighing idler of the belt scale is a key component for guiding the belt and is installed on The weighing sensor under the idler roller is the most critical part of the belt scale for instantaneous measurement of the material passing through the idler roller. [0003] The existing belt scale uses a motor to drive the belt on the idler roller, and pours the material onto the upper surface of the belt. When the conveyor belt carrying the material passes the idler roller, the idler roller plays a role of supporting and guiding the conveying belt. At the same time, the load cell installed insid...
